Uboot & ATF

The OpenWrt/24.10 or trunk image type is ITB, which cannot be loaded if the original U-Boot is too old. Please update to a newer U-Boot that supports both OpenWrt 21.0x and OpenWrt 24.xx image types. The minimum required version is 2024-08-07.

• Since U-Boot is still released as a tarball, please log in to the DCC or contact the corresponding window to obtain the latest U-Boot and ATF source code.

SPIM-NAND

Note: Please follow the SOP below to upgrade the bl2 and fip on your board.
